![]() ![]() Along with the modern IDE, it is usually required to be able to understand and use the features of Fortran. It is important for most programmers to be able to work withing a modern IDE, as many organizations require teams to collaborate around projects created in these environments. It is now possible to use graphical Integrated Development Environments (IDEs) to develop, compile, run, and debug Fortran programs. The real problem is the closer you get to NASA TRL 9 the fewer mistakes you are allowed and really if it makes a mistake it has to be self correcting.Many programmers want to upgrade their skills to be able to write and maintain Fortran programs on a variety of systems, including Windows, Mac, and Linux. The problem with the 6100 is the watcher does not restart the main program from time to time, but now I have a machine that is doing this about every 24 hours, so I can start to look at the issue, before it might last a month, very hard to debug a monthly problem. The exe container is a watcher program - the main program is multithreaded - connected to a mysql database in the cloud and reading data from a source - it crashes from time to time on some machines, which is the reason for the standard watcher program. The main contributor of those huge variations is a performance measurement process itself, the other factors are mainly OS-kernel generated (context switching, thread migration, periodic apic timer activity, interrupt handling) and HW-oriented (voltage ramp up, frequency throttling, and other thermal events). The distributions are not-normal and usually for 100 runs are of muli-modal type. On daily base I measure the performance of our L1-PHY (5G physical (upper) layer) simulation and I saw a huge variations of the same test module results gathered by VTune (perf collector, and sep5.ko collector). Unfortunately (from the performance analyst perspective) that is true. Or modern Linux, although we are having trouble with Linux and ethernet issues, you will have the same issues, we see this on NUCs PI,s and DELLS. You are wasting your time, get a better computer and a better compiler and a modern Version of Windows, say version 20211 and you will get better results. Two runs one after the other can vary a lot. I will explain if required, we have probably 10 million records, if I normalize my results and your results then you are within what I would call expected limits.Ĭomputers do a lot of things you do not see and that affects run time. We record the loop time of the run time, in each loop, a loop is about 8 seconds, the loop time is observed to be a non-Gaussian distribution, which is often the problem with data generated by computers. I run a single program on multiple computers across the world. ![]()
